摘要：
Electronic structure of Tl2Ba2Can-1CunO4+2n superconductors for n = 1, 2 and 3 has been studied. Dimeric [Tl4Ba12Ca6n-6Cu2nO16+7n]2n-8 units have been investigates using the quasirelativistic INDO molecular orbital method. The dependences of d-electron populations, atomic charges, Wiberg indices, the density of state (DOS) function and its d-orbital projection on the number, n, of CuO2 layers in the unit cell, exhibit some interesting trends. © 1990.
